They create a beam angle of 115° FWHM (full width at half maximum). Light distribution curve C 0° 75° 60° 45° 30° 15° 2.2 Light modulation The AC technology of the PrevaLED® Flat AC results in a light modulation with a frequency of 100 Hz. Capacitors are placed into the PrevaLED® Flat AC module to reduce the modulation of the light output. The resulting light modulation has a depth of 30 %. The luminous flux of the LED module never drops below 70 %. 5 PrevaLED ® Flat AC light engines | Optical considerations 2.3 Homogeneity To get an overview of the resulting homogeneity in slim luminaire designs, the following images show the results in illuminance and color appearance at different distances between the light engine and the diffuser. The images have been obtained through simulation, assuming an ideal diffuse cover. The simulation has been performed with a 170-mm-diameter PrevaLED® Flat AC module and a 200-mm-diameter diffuser cover. The following image shows the simulation set-up. Simulation set-up Simulation results D = 15 6 PrevaLED ® Flat AC light engines | Optical considerations D = 25 D = 35 7 PrevaLED ® Flat AC light engines | Optical considerations D = 45 D = 55 The simulation results show that the homogeneity values do not further improve when the distance between the PCB and the ideal diffuser layer is 45 mm or more. OSRAM provides mechanical (3D files) and optical simulation data (ray files) to support customized reflector designs. Mechanical files can be downloaded at www.osram.com/prevaled.

Please ensure that the housing of your luminaire provides the IP protection required for your application. To achieve an ingress protection rating of IP20, it is possible to combine PrevaLED® Flat AC light engines with the available touch protection accessory. For further information, please have a look at the technical application guide “IP codes in accordance with IEC 60529”, which can be downloaded at www.osram.com. 4 Electrical considerations 4.1 Wiring information PrevaLED® Flat AC light engines can be directly connected to mains voltage (220–240 V, 50/60 Hz). The used input clamps can handle solid or flexible wire with a crosssection of 0.5 to 1.5 mm2 (AWG20–16). The use of solid wire is recommended. Wire preparation 6–8 mm (0.24–0.31 inch) Please insert the wires in 0° orientation to the PCB. Notes: — The connector is designed for three poke-in and release cycles. — Due to the fact that you are dealing with mains voltage, you must not hot-plug the light engine. — The installation of LED light engines needs to be carried out in compliance with all applicable electrical and safety standards. Only qualified personnel should be allowed to perform installations. Solid wire: Plug directly. Flexible wire: 1. Lightly press the push button of the connection clamp. 2. Insert the flexible wire. To press/release the clamps, please use a small screwdriver or a Wago operating tool type 206-861. 10 PrevaLED ® Flat AC light engines | Electrical considerations 4.2 Insulation requirements The PrevaLED® Flat AC module has reinforced insulation towards the back of the PCB. The module has no insulation measures to the electronic components on the top side of the module. When the light engines are used in protection class I luminaires, the luminaire manufacturer has to ensure basic insulation of the module and all live parts during the installation of the luminaire. It is also possible to use the optional touch protection accessory in order to provide the basic insulation of the module. Please refer to chapter 7.4 for additional information on the available touch protection accessory. 4.5 Controllability Due to the integrated drive electronics, a good compatibility with all available phase-cut dimmers cannot be ensured. 4.6 Power as a function of voltage The nominal voltage of the light engine is 230 V. The operating range is 220–240 V. For voltage variations, the light engine is tested according to IEC/EN 61000-3-3. Please note that the power of the light engine changes over the voltage range. Please have a look at the diagram below for the power as a function of voltage. PrevaLED ® Flat AC 1500 lm When the light engines are used in protection class II luminaires, the manufacturer has to ensure basic insulation of the module and all live parts during the installation of the luminaire. Moreover, it is necessary to provide additional insulation in the area of the input connector. Between connection wires with basic insulation and touchable metal parts or the heat sink, a second insulation layer is required. Within the module, the creepage and clearance distances (to the mounting points and the edge of the module) for reinforced insulation are fulfilled. % Pel [W] Phi [lm] Pth [W] 130 120 110 100 90 80 70 60 50 170 180 Keep-out areas for creepage and clearance distances 190 200 210 220 230 240 250 260 270 280 Voltage [V] 4.3 Inrush current and system installation Due to their electronic construction, the PrevaLED® Flat AC light engines have a minimum inrush current. In system installations, the number of light engines which can be attached to one circuit is limited by the voltage drop regulations and the used cross-section of the connecting wire. 4.4 Electrostatic discharge (ESD) PrevaLED® Flat AC light engines fulfill the requirement of the immunity standard IEC/EN 61547. Please note that an electrostatic discharge of greater than 2 kV HBM can cause damage, ranging from performance degradation to complete device failure. OSRAM recommends that all PrevaLED® Flat AC light engines are handled and stored using appropriate ESD protection methods. 11 PrevaLED ® Flat AC light engines | Thermal considerations 5 Thermal considerations The proper thermal design of an LED luminaire is critical for achieving the best performance and ensuring the longest lifetime of all components. Due to the high efficacy of PrevaLED® Flat AC light engines, only a partial amount of the introduced electrical power has to be dissipated through the back of the light engine. The thermal power that has to be dissipated for PrevaLED® Flat AC light engines is given below. 5.4 TIM and other accessories Due to the high efficiency of the PrevaLED® Flat AC modules, the use of a thermal interface material (TIM) is not required. By using a TIM, an even better thermal connection of the light engine to the heat sink can be achieved. Note: A thermal design must always be confirmed by performing a thermal measurement in steady-state condition. 5.1 Thermal power values Product reference Typical Maximum Max. allowable thermal thermal thermal power power resistance [W]1) [W]1) R th [K/W] 2) PL-FLAT-AC-G1 1500-830 230V 8.8 9.7 6 PL-FLAT-AC-G1 1500-840 230V 7.9 8.7 6.6 PL-FLAT-AC-G1 2500-830 230V 16.2 17.8 3.4 PL-FLAT-AC-G1 2500-840 230V 13.9 15.3 3.9 1) Value measured at the tc point at a reference temperature (tr) of 70 °C. 2) Value measured at the rear of the luminaire at an ambient temperature of 25 °C. 5.2 Thermal power over voltage Please note that the thermal power of the module is related to the line voltage. Please refer to the diagram in chapter 4.6. 5.3 Thermal shutdown A thermal protection feature serves to achieve the best possible lifetime of the module and to protect it from damage by overheating. The characteristics of the thermal protection are shown in the following diagram.

The tc point is located on the top side of the light engine (see schematic drawings below). Examples of suitable thermocouples: K-type thermocouple with miniature connector tc point Different thermocouples Illustration Description Temperature range [°C] PVC-insulated -10 … +105 thermo couple Location of the tc point (on/off and L-EM version) Note: tc according to IEC 62031 stands for case temperature, which is the highest permissible temperature measured at the tc point. The tc point is the location where the tc is measured (see drawings above). A correct temperature measurement can, for example, be performed with a thermocouple. Use a thermocouple that can be glued onto the light engine. Make sure that the thermocouple is fixed with direct contact to the tc point. PFA-insulated -75 … +260 thermo couple To ensure a direct contact between the thermocouple and the PCB, it is recommended to either glue the thermocouple onto the PCB or solder it to the tc point. You can, for example, use an acrylic glue, such as Loctite 3751. Mounting of a thermocouple Mounting of a thermocouple (close-up) Note: Please keep in mind that you need a direct contact between the thermocouple and the PCB. 13 PrevaLED ® Flat AC light engines | Lifetime and thermal behavior 6 Lifetime and thermal behavior 6.1 Cooling PrevaLED® Flat AC light engines do not necessarily need to be attached to a heat sink. Depending on the application, however, a suitable cooling solution (e.g. a heat sink or luminaire housing) might be needed to keep the tc point temperature below the allowed maximum and therefore ensure a safe and reliable operation. 6.2 Flux as a function of temperature The luminous flux of PrevaLED® Flat AC light engines depends on their temperature. 100 % of the luminous flux is achieved at the reference temperature of 75 °C (tr = 75 °C). This temperature has to be measured at the tc point. If the reference temperature increases, the light output decreases. The luminous flux changes in relation to the reference temperature according to the following diagram. Flux as a function of temperature Flux [lm] Pel [W] Phi [lm] Pth [W] 108 6.3 Lifetime as a function of temperature For the definition of the lifetime of a light engine, please refer to IEC/PAS 62717, where the following types are defined (examples): — L0C10 is the lifetime where the light output is 0 % for 10 % of the light engines. — L70F50 is the lifetime where the light output is ≥ 70 % for 50 % of the light engines. F value includes reduction of lumen output over time including abrupt degradation (flux = 0). — L70B50 is the lifetime where the light output is ≥ 70 % for 50 % of the light engines. B value includes only gradual reduction of lumen output over time (not the abrupt degradation of flux). If the performance temperature (tp) is maintained, PrevaLED® Flat AC light engines have an average lifetime of 50 000 hours (L70B50). The maximum temperature measured at the tc point must not exceed 85 °C. Note: Higher temperatures lead to a shorter lifetime of the PrevaLED® Flat AC light engines. Moreover, the failure rate will also increase. 106 The table below shows the lifetime of PrevaLED® Flat AC light engines according to IEC/PAS 62717. 104 102 100 98 96 94 92 90 20 30 40 50 60 70 80 90 100 tc [°C] PrevaLED ® Flat AC 240 mm L70B10 L70B50 L80B10 L80B50 L0C10 L0C50 L70F10 L70F50 L80F10 L80F50 Lifetime [h] at t p = 45 °C 35000 50000* 22000 43000 50000* 50000* 34000 50000* 21000 43000 Lifetime [h] at t p = 55 °C 31000 50000* 18000 37000 50000* 50000* 29000 50000* 18000 36000 Lifetime [h] at t p = 65 °C 26000 50000* 16000 32000 50000* 50000* 25000 50000* 15000 31000 Lifetime [h] at t p = 75 °C 23000 46000 13000 27000 50000* 50000* 21000 44000 13000 27000 * Expected to be higher PrevaLED ® Flat AC 170 mm L70B10 L70B50 L80B10 L80B50 L0C10 L0C50 L70F10 L70F50 L80F10 L80F50 Lifetime [h] at t p = 45 °C 48000 50000* 30000 50000* 50000* 50000* 46000 50000* 29000 50000* Lifetime [h] at t p = 55 °C 42000 50000* 26000 50000* 50000* 50000* 39000 50000* 25000 50000 Lifetime [h] at t p = 65 °C 36000 50000* 22000 44000 50000* 50000* 33000 50000* 21000 43000 Lifetime [h] at t p = 75 °C 31000 50000* 19000 38000 50000* 50000* 28000 50000* 18000 37000 * Expected to be higher 14 PrevaLED ® Flat AC light engines | Mechanical considerations 7 Mechanical considerations 7.1 Outline drawings The following schematic drawings provide further details on the dimensions of PrevaLED® Flat AC light engines.

Please apply force only to the dedicated mounting positions. Strong mechanical stress can lead to irreversible damage of the light engine. kg Note: Please do not touch or mechanically stress any component of the light engine. This could damage the light engine. 7.5 Protection from corrosion To protect electronic parts (such as LEDs) from corrosion, a corrosive atmosphere around the components has to be avoided. In case of LEDs, H2S, for example, is a highly corrosive substance which can lead to a drastically shortened product lifetime. The source for H2S are sulfur-cross-linked polymers, such as rubber. To ensure the absence of H2S, it is recommended to use peroxide-cross-linked materials, which are available on the market as an alternative to sulfurcross-linked versions. Avoidance of corrosion by moisture has to be ensured by the appropriate protection of the luminaire housing (see chapter 3 “Ingress protection”). 7.6 Mounting To mount a PrevaLED® Flat AC light engine (with or without touch protection accessory), use M4 cylinder head screws according to DIN 912 or ISO 4762. The torque is 1.0 (±0.5) Nm. 7.4 Touch protection accessory To protect the light engine from contact and to provide a basic insulation, an additional touch protection accessory is available for PrevaLED® Flat AC light engines. Note: In combination with the touch protection accessory, a PrevaLED® Flat AC light engine has reinforced insulation to the back and basic insulation to the top. 3D fi les of the touch protection accessory Mount PrevaLED ® Flat AC from the top It is also possible to mount the touch protection accessory after the PrevaLED® Flat AC light engine has been screwed to the heat sink/luminaire. Please refer to the insulation requirements in chapter 4.2.
